Ahhhhh... grasshopper... the question is for the muses.

Nahhh... remember I did all the laborious collection of data about the sheath stamps. I have a data base that is pretty huge, so big I forget where some things are.

From my previous study, IT IS MY IMPRESSION that the model 1 apparently had the largest supply of Heiser sheaths in the bins when the switch from HLK to Johnson occurred. Thus the supply of Heisers for model 1s seemed to have lasted longer into the '60s, and were being shipped even after the switch over to baby dots on other models. However, it may be all an impression, not supportable by a hard look.

If I remember correctly, the "proof" involved looking at the sheaths delivered with SS knives of different models. I noticed that ... say ... model 2s and 3s with an SS were being delivered in baby dots when some model 1 SS knives were still being shipped in brown button HLKs. or something along that line.

I tried to picture how the operation ran. My picture was ... when a knife was finished, someone took it to the sheath bin, tried a few sheaths until one was found that fit resonably well. He then installed the keeper snap, boxed and labeled it ... zoom ... out the door. It would be reasonable to have sheath model overlap if there were a large supply of sheaths for a particuler model on hand, and more coming in. I seem to remember that model 2 HLK sheaths seemed to be in especially short of supply, switch over to Johnson progressed through all varients or something ... whatever ...
